Almost always a neutral aerial, though sometimes a back aerial, the signature aspect of a sex kick is that they are stronger during the initial thrust and weaker afterwards (with the exception of Dr. Mario's sex kick, which is weaker in the first few frames). In Brawl, the initial hit can connect for only the first frame of the attack. While some sex kicks only have one hitbox for the thrust, others have a series which grow progressively weaker. Other typical attributes of a sex kick include low startup time and landing lag.
Although the term classically refers to only neutral aerials, smashers often extend its usage to other aerial attacks with similar properties, such as Fox's back aerial in Melee. Captain Falcon's Knee Smash is an extreme example of a sex kick, with enormous power when it first comes out and little knockback after the strong hitbox has faded.
The term "Sex Kick" was created by the smasher and ex-tournament director Matt Deezie, as a sexual innuendo referring to the properties of the attack in the original Super Smash Bros (initial thrust and extension). Despite being offensive to many players, the term is widely accepted by the competitive smash community.
